Unfiled tax returns? Catch up with the IRS from Nashville

Normally six. IRS Policy Statement 5-133 (IRM 1.2.1.6.18) says its delinquent-return procedures will normally be enforced for not more than six years, and that going further back requires a manager’s approval.

The six years are policy. The statute itself sets no deadline for an unfiled year: under 26 U.S.C. § 6501(c)(3), when no return is filed the IRS may assess the tax at any time. An older year therefore stays open and can still be requested. Six years is the usual starting point for a catch-up, and the IRS transcripts show whether your account fits that pattern.

The firm’s posts on unfiled returns make the same point about pace: “You do not need to fix every year at once.” The order matters more than speed, and it comes from reading the IRS transcripts to see what the IRS already has.

A Substitute for Return (SFR) is a return the IRS prepares for you under 26 U.S.C. § 6020(b), from what employers, banks and other payers reported. The Internal Revenue Manual says deductions and credits are not allowed on an SFR, apart from the standard deduction for an individual. The IRS’s own guidance warns that it “might not give you credit for deductions and exemptions you may be entitled to receive.”

For a self-employed person that can mean tax figured on gross receipts from Forms 1099, with no business expenses taken out. Filing your own original return for that year gives the IRS correct figures to work from, and it generally adjusts the account to match. That makes an SFR year a natural place to start, since it is the year where the IRS’s number may sit furthest from the real one.

Two penalties under 26 U.S.C. § 6651 do most of the damage. Failure to file adds 5% of the unpaid tax for each month or part of a month the return is late, up to 25%. Failure to pay adds 0.5% a month, also up to 25%. In a month when both apply, the filing penalty is reduced by the payment penalty [§ 6651(c)(1)]. Interest runs on top of both.

The filing penalty reaches its cap after five months, so on an old year it is already at 25%, while the payment penalty keeps adding to the balance for years. Both are percentages of unpaid tax. A year in which withholding covered the tax carries no failure-to-file penalty at all, which is one reason the transcripts are read year by year before anything is prepared.

Only if you file within three years of that return’s due date. The IRS says a refund of withholding or estimated tax, and refundable credits such as the Earned Income Tax Credit, can be claimed only on a return filed within that window. After it closes the money stays with the Treasury.

In a six-year catch-up this puts the newest years under a clock of their own. A wage earner who had too much withheld in a recent year can lose that refund simply by waiting, so those years may be prepared alongside any SFR year.

Tennessee adds little to the catch-up. The Hall tax, the state’s only individual income tax, never reached wages. It covered bond and note interest and stock dividends, and it ended with the 2020 tax year, so a missing Tennessee year is a federal problem only. A Kentucky resident has state returns to file as well, at a flat 3.5% for 2026.

A catch-up starts with Form 2848 and the IRS transcripts, which show which years the IRS expects a return for, what income was reported, and where an SFR has already been assessed. Tyrone J. Taylor then prepares the missing returns in the order the deadlines require.

Filing is also the entry ticket to every resolution. An Offer in Compromise is not considered until all required returns are filed, and the IRS’s online long-term payment plan requires the same, so the balance the returns produce goes straight into the installment agreement or offer that follows. One client, JonTrelle R., described the experience simply: “Tyrone has helped me tremendously with all of my tax issues. He is quick on responding”.

All of this is general information, and how many years you need depends on the facts of your account.
